systemConfig/5xx_board_init.c:104 internal compiler error: in emit_move_insn, 
at expr.c:2809

gcc version 3.4.0-macraigor1

GNU C version 3.4.0-macraigor1 (powerpc-elf)
compiled by GNU C version 3.3.1 (cygming special).
I didn't configure GNU, Macraigor did, I didn't even know one could configure 
it, I haven't seen documentation on this.

command line is in file bug.rpt

I don't see how to attach the files you have asked for:

I'm running GNU on a Dell 8400 with WindowsXP and cygwin.

Confirmed. This is triggered by a bogus argument for an output constraint.
Not a regression.

Where can I find some documentation on using this extended asm format? I
have read all the GNU docs on it and can not understand how to use it.

Thanks,

Dave

Well, those docs are all we have. If you have any more concrete criticism,
feel free to file a bug about it.

[Bug inline-asm/20382] internal compiler error with bogus asm output constraint

[sailors3 at comcast dot net]

------- Additional Comments From sailors3 at comcast dot net  2005-03-09 12:00 -------
Subject: RE:  internal compiler error with bogus asm output constraint

Hello,

I apologize if my question sounded like criticism, It is really more of a
reflection on me (my ability to learn) than on GHU. 

I'm trying to get the compiler to accept this asm instruction:

/*		asm("ori		r5, r5, (ARCH_MSR_ME |
ARCH_MSR_RI)");*/

Using extended asm as this:

		__asm__ ("ori	%0,%1,%2"
				: "=r" ("r5")
				: "0" ("r5"), "g" (ARCH_MSR_ME |
ARCH_MSR_RI));

And the compiler is giving me:

Error: assignment of read-only location
Error: incompatible types of assignment

I guess I'm not properly interpreting the documentation on how to use
registers in the asm, is that correct?

Thanks,

Dave

Yes, that's correct :-) I suggest you ask at gcc-help@gcc.gnu.org, preferably
stating what it *really* is that you want (why do you want to generate this
asm?).
